[quote=P.M.]Speedpuck is a valuable tool when racing, especially WL courses. It shows subtle shifts keeping you in tune when your getting knocked enough to tack, or when you are getting lifted, and also micro changes in speed.

As for recreational sailing probably won't do much for you other than give you a heads up display of speed.
